Where Does Katharine Get This Tripe From?

December 19, 2011




According to Katharine Hayhoe, there has been a 50% increase in precipitation in the Northeastern United States.

Not according to NOAA, Katharine.



In her interview with Yale 360, Katharine tells us :-

The Northeast is particularly vulnerable to heavy precipitation events, not just rainstorms, but snowstorms. We’ve already seen a 50-percent increase in precipitation in the Northeast. It’s very vulnerable to flooding; there have been an enormous amount of flooding events in the Midwest and Northeast.

A simple check with NOAA confirms this claim is not true.

Annual Precipitation
Northeast Region

Annual 1895 – 2010 Data Values:

Annual 1901 – 2000 Average = 41.08 Inches
Annual 1895 – 2010 Trend = 0.47 Inches / Decade



There has been an increasing trend, but since 1895 the rate of increase of 0.47” per decade equates to about 12%. No matter where you cherry pick a starting point, you don’t get much more than this figure. Katharine seems to be making a habit of making statements that cannot be substantiated.

    lol, she’s probably measuring from 1965. She’s a funny girl.

      It is very important in Climate “Science” to carefully pick your dates!

      I was ready for that one , James!!

      From 1965 it works out at 1.34″ per decade, i.e about 15%.(But from 1966 it only = 1.09″ – just shows how big a difference cherry picking makes).

    You need a lot more practice before you can become a warmist!

    2001 ~865mm, 2002 ~1290mm

    Result: 50% increase.

    Ta da!
